The red dots appear because of a software or hardware issue.
The red dots appear because of a software or hardware issue.
I noticed some small red dots appearing on your screen, especially in low light. When you switched the HDMI port on the TV, it worked for a day. Now it seems the issue is with the TV itself—when using the system mode, nothing appears, and changing the port to HDMI 2 showed blue dots instead of red. This looks like a display or driver problem.
